The point of increased automation is to increase the value of human labor. Just like Excel hasn’t eliminated accountants so too will future people have far greater and greater tools. Slowly bad jobs will be eliminated and quality of life will improve because of cheaper costs. In the middle ages more than 50% of the world population were farmers. Are there less farmers now? Yes, are there less jobs because of it? No

It seems you have RIGHT and GBUF broken out to a lineout type output. The GBUF (around 1.23 V) is appropriate for headphones but I’m concerned about connecting it to the amplifier ground since it would have to source enough current to set the amplifier’s ground potential to a 1.23 V. Is it safe to assume that the load on the IC will be minimal/safe?
I was working on a project involving the VS1053 and an amplifier when I saw this video, previously I had planned to use bypass capacitors on the LEFT and RIGHT channel and set the amp ground potential to analogue ground but it seems this may be unnecessary and I could just use GBUF instead. Have you experienced any problems in doing this?
